This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is transmitted from person-to-person by close contact, small aerosol respiratory droplets and potentially via contact with contaminated surfaces. Here, we investigated the effectiveness of commercial UVC-LED disinfection boxes in inactivating SARS-CoV-2 contaminated surfaces of personal items. We contaminated glass, metal and plastic samples representing the surfaces of personal items such as smartphones, coins or credit cards with SARS-CoV-2 formulated in an organic matrix mimicking human respiratory secretions. For disinfection, the samples were placed at different distances from UVC emitting LEDs inside commercial UVC-LED disinfection boxes and irradiated for different time periods (up to 10 minutes). High viral loads of SARS-CoV-2 were effectively inactivated on all surfaces after 3 minutes of irradiation. Even 10 seconds of UVC-exposure strongly reduced viral loads. Thus, UVC-LED boxes proved to be an effective method for disinfecting SARS-CoV-2 contaminated surfaces that are typically found on personal items.
